To all whom it may concern:

Be it known that I, FREDERICK R. OLIVER,

a citizen of the United States, residing at San Francisco, in the county of San 'Francisco and State of California, have invented certain new and useful Improvements in Cooling Apparatus, of which the following is a specification, reference being had to the accompanying drawings. 7

.This invention relates to an improved cooling apparatus for root beer and similar beverages and has for its primary object to provide simple and eficient means for cooling the beverage as it is dispensed from the container or receptacle.

It is a more particular objectof the invention to provide an apparatus for ,the above purpose embodying an outer barrel or container having double walls, a receptacle supported-within said container, said receptacle being of such form and dimensions as to provide'an ice compartment within the container, a-dispensing valvemounted upon the container wall, a pipe coil within the ice compartment connected to the container and to the valve, and a second pipe coil in said compartment connected to the valve at one of its ends and adapted to be connected at its other end to a pressure tank containing carbonated water or other liquid.

It is a further general object of the invention to improve and simplify the construction of apparatus of the above character and render the same highly serviceable and convenient in practical use and capable of manufacture at relatively small cost.

With the above and other objects in view, my invention consists in the novel features of construction, combination and arran ment of parts to be hereinafter more fu ly described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 is a it rtical sectional view of a liquid coolin ap ratus constructed in accordance wit the preferred embodiment of my invention;

, Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1;

Fig. 3 is a top plan view, the cover being partly broken away; and v n I Fig. 4 is an enlarged detail vertical section showing the means for mounting the receptacle within the barrel or container.

Referring in detail to the drawing, 5 desitgnates generally the container which is pre erably of barrel shape form as shown,

This receptacle,

and has a head 6 permanently fixed in one end thereof. Within this container 5, a cylindrlcal shell 7 is arranged, said shell bemg preferably constructed of sheet metal and ppenatits upper end. Suitable sup porting feet 8 are provided upon-the bottom of the shell 7 to space the same from the bottom 6 of the container. A spacing ring 9 is arranged between the. u per open end of the shel 7 and the wall of the container 5, said ring fitting into a V-shaped groove or chime in the container wall, and said spacing ring and the shell 7 being fixed to said wall by means of screws, bolts, or other suitable fastening elements. The shell 7 is provided adjacent to its lower end with a laterally projecting outlet neck 10 extending through an opening in the wall of the barrel or container 5. Upon the outer end of this neck 10, a dispensing-valve 11 is suit-- ably mounted or connected.

Within the shell 7, the receptacle 12 for the root beer or other liquid is arranged. as shown in Fig. 2, is of substantially semi-circular form in'plan and is spaced from the side and bottom walls of ,the shell. A plurality of screws 13 extend through the side walls of the receptacle adjacent to its upper end and through openingsin the shell 7, the outer ends of said screws being threaded in the wall of. the barrel or container 5. The pipes 14 are also connected to the receptacle adjacent its u per and lower ends and extend outward y through the shell 7 and the container wall, and to the outer ends of said tubes the upper and lower ends of the gage glass 15' 1s suitably coupled, whereby the quantity of liquid in the receptacle 12 may be readily ascertained. .The space within the shell not occupied by the receptacle 12, constitutes an ice compartment, and broken ice is adapted to be packed therein beneath said receptacle and around the same. To the inner side of said receptacle, at its lower end, one end of a pipe coil 16 is connected, and the other end of said coil extends out- I wardly through the neck 10 and is connected tothe bore or passage of'the valve 11. T1118 105' coil is disposed entirely at one s1de of the to the end of this latter pipe coil 17 extends down .wardly through a tube or nipple 18 centrally mounted in the bottom 6 of the container 5 and in the bottom wall of the shell 7. A hose or tube extending from a pressure tank is connected to this latter end of the pipe coil and supplies carbonated water or other liquid to the pipe coil. .A drain or waste pipe 19 extends some distance above the bottom wall of the shell 7 and downwardly through the bottom 6 of the container, so as to permit a suflicient amount of ice water to remain in the bottom of the shell 7 and partially cover the pipe coils.

Asbestos or other suitable packing material is tightly packed into the lower end of the container 5 around the shell 7 to conserve the ice and prevent the too rapid melting thereof. The root beer or other syrup is pumped through a pipe, indicated at 20, which extends up through the bottom of the container 5 and through the shell 7 into the receptacle 12 to a point adjacent the upper end of the latter. This pipe, at its lower end projecting through the bottom of the container 5, is equipped with a suitable threaded coupling for connecting the hose or other conduit thereto extending from the source of supply.

The top or cover for the container 5 consists of two similar semi-circular wood sections 21 which are hingedly connected along their straight edges, as at 22. A metal plate 23 is secured upon the top surface of each of these sections 21 and projects beyond the outer edge thereof to provide a marginal flange adapted to seat upon the upper edge of the container wall. It will be understood that the receptacle 12 which is preferably constructed of porcelain, may also be provided with a removable cover or closure.

Within the barrel or container 5, between the wall thereof and the shell 7, a casing 24Lv is suitably secured to the container wal and a glass plate 25 containing suitable advertising matter is arranged in the wall of the container opposite this casing. Artificial illuminating means, indicated at 26 is provided within the chamber back of t is plate. A pipe 27 leads from the top of the casing 26 upwardly through an opening in one of the top or cover sections 22 to exhaust the heated air from said casing. As this advertising device constitutes the subject-matterof a separate application for patent filed August 2, 1916, Serial No. 112,883, the same will not be further referred to.

From the foregoing description, taken in connection with the accompanying drawing, it is believed that the construction, manner of operation and several advantages of my improved cooling apparatus will be clearly and fully understood. By means of the same, ice-cold mixed drinks may be quickly served while the expense incident to the refrigeration or the cooling of the liquid is relatively small. It is apparent, of course, that the apparatus may be manufactured in various sizes and also of other shapes than that shown in the accompanying drawing. The invention is also susceptible of many modifications in the form, proportion and arrangement of the several detail parts and I, therefore, reserve the privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is 1. A cooling apparatus including a container having inner and outer spaced walls, a liquid receptacle arranged within the container, means for sustaining said receptacle with its side and bottom walls spaced from the corresponding walls of the container to afford an ice compartment between said walls, the inner wall of the container having a laterally projecting outlet neck extending through an opening in the outer container wall, a valve operatively connected to said outlet neck, a pipe coil arranged in the bottom of the ice compartment and conneoted at one of its ends to the liquid receptacle and at its other end to said valve, and a drain pipe extending through the bottom walls of the container and above the plane of the pipe coil therein. v
